Issue / Question:
5 amp fuse on interior fuse panel (#15?) blows immediately. Short to ground can’t be found. I think fuse is for RABS, GEM Module? Inop items are interior lights, seat belt reminder, wipers, horn, electric windows, and will not shift out of park after engine started. Any idea where to look? Have checked wiring on frame, engine compartment, firewall plug connection, isolated brake light on/off switch, Transmission Range switch, drivers door panel electric window rocker switches, wiring on lower door sill under carpet checked. Have seen this problem before?

Maybe a door latch switch! Seen the switch go bad and cause it to short out and blow fuse when you shut the (most likely the drivers door).
Try a 10 amp fuse if history repeats itself I would pull the door panel and look at the drivers door latch switch.
